Applied Materials Falls 4%, Lam Research and Teradyne Sink 5%: What’s Prompting the Selloff in Chip Equipment Stocks?

Applied Materials (AMAT) fell 4% to $494.82, while Lam Research (LRCX) and Teradyne (TER) dropped 5% amid concerns over AI infrastructure spending. The selloff comes despite a decline in long-end Treasury yields, which typically benefits growth stocks. Anthropic and OpenAI reported lower-than-expected revenue run rates, fueling doubts about AI capex durability. The iShares Semiconductor ETF (SOXX) is up 77% YTD, but individual equipment stocks have seen larger gains.
